592 Questions
Is the speed of sound in air is about 343 meters per second?
Yes, the speed of sound in air at room temperature is approximately 343 meters per second. The exact speed can vary depending on factors like temperature, humidity, and air pressure.
If you break the sound barrier do you hear the boom again once you slow down?
Yes. If you were to slow to subsonic speeds, the boom can catch up to you, and you would hear it.
Why is glass wool used to sound proof the room?
In clear unobstructed air sound can be heard very clearly, very far away. When sound encounters glass wool or any other obstruction then sound is slowed down to a great degree or stoped altogether.
What does a pitch of sound depend on?
The pitch of sound depends on the frequency of the sound wave. Higher frequency waves result in higher pitch sounds, while lower frequency waves result in lower pitch sounds.
Sound waves travel by vibrations in what?
Sound is energy of mechanical vibration transferred through a medium.
Commonly the medium is air, but solids, liquids and gasses all transmit sound. Indeed, sound travels faster through liquid and solids than through gas.
Sound does not propagate through a vacuum.
What are some Factors that affect speed of sound in air?
Think mainly of the temperature and a little bit of the humidity.
Speed of sound in air is c ≈ 331 + 0.6 × T.
T = Temperature in °C.
Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
What do you call an aeroplane that travels faster than the speed of sound?
With modern technology, there are many planes that can travel faster than the speed of sound, including many fighter planes and a few airliners.
Any aircraft that flies faster than 1 Mach is faster than the speed of sound.
Almost all modern day fighters travel at speeds in excess of the speed of sound. That includes the Russian MIGS from mig17 on, French Mirage, All US fighters.
The planes which can fly at the speed of sound are SR-71, Mig-25, F-16, F-18, F-22, Sukhoi Su-47 and many others.
no, not necessarily. the reason that the sound appears to be coming from way behind the jet is because light travels faster than sound. think of a firework show, the sound always comes after the flash depending on how far away you are. since the jet is far away, by the time the sound reaches you, the jet is already way out ahead of the sound. this might help.

It can be calculated in a simple manner.
The formula for finding it is: V(t) = Vo + 0.61t
This formula shows that for one degree rise in temperature, the increase in velocity will be 0.61m/s
Is speed of sound proportional to distanced traveled?
No. The amplitude of the sound (and therefore its loudness) will decrease at greater distances; the speed will remain constant (assuming other factors, such as the density of air and the temperature, are constant).
Why is Chuck Yeager important to California?
He continues to epitomize The Right Stuff!
Major General Charles Elwood (Chuck) Yeager, retired, is among the greatest pilots who has ever lived. He performed most of his test pilot work in California at Muroc Army Air Field, now Edwards Air Force Base. He broke the sound barrier on October 14, 1947 there, and was the head of the Aerospace Research Pilot School, the precursor to Air Force Flight Test Center, at Edwards AFB. He helped with the training of all of the early astronauts.
"Chuck" first learned to fly in California and met his first wife Glennis (now deceased) in Oroville, CA.
He has lived in California since 1975 and has raised a lot of money for various non-profits in California.

Does sound travel through metals faster than it does through nonmetals?
no this a opaque material
opaque is a material where light cannot pass through
so it cannot pass through
What is the difference in the speed of sound at 0 degrees C and the speed of sound at 25 degrees C?
At 0 degrees C, the speed of sound is about 331 m/s, while at 25 degrees C, the speed of sound is around 344 m/s. The speed of sound increases with temperature because sound waves travel faster in warmer air due to increased molecular motion.
What travels faster airplanes or speed of sound?
The speed of sound does not travel.
In the event that an airplane's airspeed is below Mach-1, the speed of sound is faster
than the speed of the airplane.
On the occasion and at the moment when the true indicated airspeed of an airship or
an airplane is in excess of Mach-1, the airplane is at that time traveling faster than the
speed of sound.
What would happen if a spherical volume of air instantaneously disappeared?
It depends on the size of the disappearing sphere. If a small sphere disappeared then air from adjoining space would move in and balance would soon be be restored. However, if a large sphere disappeared then the adjustment could involve extreme turbulence.
What is the difference between sound waves and earthquake waves?
Sound waves are generated by vibrations in air or a medium and travel in all directions from the source, whereas earthquake waves are generated by the sudden release of energy in the Earth's crust and travel through the Earth. Sound waves are longitudinal waves that can travel through gases, liquids, and solids, while earthquake waves consist of P-waves (compressional waves) and S-waves (shear waves) that travel at different speeds and have different effects on the Earth's surface.
Why does sound travel faster in dense material?
Dense materials usually mean the atoms are closer to each other. Sound waves travel by causing vibration and transfer of energy. The close the atoms, the easier it is to transfer the energy. As the result, sound travels fastest in solid, then liquid, the least in gas matters.
If the speed of sound is 343 meters per second what is the temperature?
The speed of sound in air changes with temperature. At 20 degrees Celsius (68 degrees Fahrenheit), the speed of sound is approximately 343 meters per second.
How does elasticity effect on speed of sound?
The speed of sound is variable and depends mainly on the temperature and the properties of the substance through of which the wave is traveling.
V=331+0.6T
where V is speed of soundwave in m/s
T is the temperature in Celsius
Chuck Yeager's plane is faster than the speed of sound was on?
Chuck Yeager became the first human to officially break the sound barrier, on 14 October 1947 in the Bell X-1. He reached a speed of at Mach 1 at an altitude of 13,700 metres.
Speed of sound equals how many km pH?
The speed of sound changes with different atmospheric conditions, but is around 340 meters per second.
That's equivalent to (340 x 3,600) = 1,224 kilometers per hour
Why does sound move faster through stone than water?
sound moves faster though stone than water because stones particles are closer together and vibrate faster.
+++ We can add that in general, the denser the material the higher the speed of sound through it.
What is the speed of sound at sea level for Tucson?
The speed of sound has neither to do with the sea level nor with Tucson.
Speed of sound has mainly to do with the temperature of the air.
Look at the link: "Speed of Sound in Air and the effective Temperature".
What happens when the plane goes faster than the speed sound?
when the plane goes faster than the speed of sound then the plane is seen first and the sound is heard after the plane has passed away. In this case the plane is having speed more than 1 mach.
